Even if you don't need a permit, your project must meet all code requirements and development standards. You can find information about electrical, plumbing, side sewer, construction, and land use permits on the Permit Types page.

Minor repairs or alterations. You don't need a permit for minor repairs or alterations that cost $6,000 or less in any 6-month period. The $6,000 limit is based on fair market value of labor and parts, even if you do the work yourself.

You need a permit for any work on load-bearing supports, changes to the building envelope, and work that reduces egress, light, ventilation, or fire resistance no matter how small the project.

Miscellaneous work. These projects usually don't require a permit:

Patio and concrete slabs on the ground (on grade)

Painting or cleaning a building

Re-pointing a chimney

Installing kitchen cabinets

Paneling or other surface finishes over existing wall and ceiling systems

Limited in-kind repair or similar replacement of deteriorated parts of a structure

Buildings and landscaping. You usually don’t need a permit for

A one-story detached accessory building such as a greenhouse, tool or storage shed, playhouse, or similar building if the projected roof area is less than 120 square feet and the building foundation is only a slab on the ground

Fences that are less than 8 feet high and have no concrete or masonry elements higher than 6 feet

Platforms, walks, and driveways. You do not need a permit for these if they are less than 18 inches above grade and not over a basement or other building story.

Roofing and siding replacement. In detached one- and two-family houses, you do not need a permit to replace existing roof sheathing or to repair the roof only you are not making changes to the building envelope and the work is as good as the existing structure.
